Question

Помогите 3+ x - Ix-1I >1

Answer 1

3+ x - Ix-1I >1
x-1=0
x=1

___________1___________

1) x≤1                           2)  x>1
   3+x+x-1 >1                    3+x-x+1>1
   2x+2 >1                         0x+4 >1           
   2x > -1                           0x>-3
   x > -0,5                          x∈(1;+∞)
   x∈(-0,5:1]

x∈(-0,5;1]∨(1;+∞)= (-0,5;+∞)
